WebTheorem: If n is an integer and n2 is even, then n is even. Proof: By contradiction; assume n is an integer and n2 is even, but that n is odd. Since n is odd, n = 2k + 1 for some integer k. Then n2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1. Now, let m = 2k2 + 2k. Then n2 = 2m + 1, so by definition n2 is odd. But this is impossible, since n2 ...
